Mapiah

Mapiah is a graphical editor designed specifically for creating and modifying cave maps generated through the Therion surveying system. It provides a dedicated workspace where cartographers can manipulate survey data vectors, station labels, and scrap outlines to produce detailed underground cartography. The application interacts directly with standard Therion project files, allowing users to build complex multi-layered cave maps from raw measurement datasets. While the software centers on Therion integration, its operational scope is tied directly to the conventions and file formats of that specific survey ecosystem.

The interface supplies vector drawing tools tailored for adjusting centerline geometry and passage walls according to speleological mapping standards. Users can manage map symbols, adjust scrap coordinates, and compile visual elements into coherent cave representations. Because it functions as part of a specialized toolchain, users must prepare their survey data through external measurement processing before importing projects into the editor for final layout work.
